Hello all,
My company makes granola and protein bars that we package in film using a flow wrapper (Think, bars go in a conveyor belt, the film is wrapped around them and then sealed and cut by the machine. We just bought a new leak detector (water submersion, vacuum chamber) for testing our seal integrity. It is a significant upgrade from the previous tank that we previously had, which was made in house by our maintenance team.
We have a single internal document that reference's the leak detection standards and there is no accompanying documentation about how the 20psi setting was determined. Can anyone provide me with some advice, or any reference documentation I could use to determine if this is the correct setting to perform this packaging test? Or is this just the kind of thing where we will need to do a bunch of trial and error and just pick whatever setting we think is going to be best? Is there any kind of industry standard or guidance for these types of tests?
Thank you!
